How much shade coverage is required. What the width of the awning should be, based on the shade area. Add at least 12 inches to maximize coverage for sun and rain protection. How far out the awning extends (the projection), based on the shade area. There is a natural slope to an awning, so the actual shade is several inches shorter than the full projection. How high to mount the awning. Because of the awnings slope, the front of the awning is lower than the mounting position; this difference is the drop. The recommended drop is 3 inches per foot of projection. So, if the awning has a 12-foot projection, the drop is about 36 inches. To get a 7-foot clearance under the front bar, the awning has to be mounted at least 10 feet high. Scout out a mounting place that is free of obstructions (no lights, gutters, wiring, or ornamentation) and has adequate clearance around any doors or windows. For screens, make sure that any doors swing away from the screen. For retractable awnings, make sure the awning can extend its full projection without running into a tree, patio, roofline, or fence.
Installation in a Few Easy Steps The general installation process for both traditional retractable awnings and drop screens is pretty simple: attach the correct number of mounting brackets using the appropriate fixing and insert the torsion (square) bar. The simplicity of installing awnings is what makes them ideal for do-it-yourself weekend projects. The exact installation steps, naturally, vary depending on the awning being installed (so always read the manufacturers specific instructions!), but these are the general processes. For a drop screen:1. Assemble the screen itself, putting together the roller (called the headerbox), similar to an old-fashioned shade.2. Install the mounting brackets at the top and around the door frame or the beam of the gazebo or porch.3. Snap in the headerbox, making sure that the bottom rail of the screen is toward the inside of the room.4. If there are vertical side guides, measure and cut them according to the height of the opening, and then screw them in place and snap them in position with the headerbox. If there are guide wires, screw the bottom brackets into place, and attach the wires to the cassette. Be sure everything is level and plumb.
Extra square footage. Retractable awnings can be used in a variety of applications and have virtually unlimited uses from ticket booths and ATM kiosks to smoking areas and employee break areas. This provides comfortable exterior spaces without extra construction costs. Tax deductible capital improvement. Municipal incentives. Retractable awnings even fall under many municipal capital improvement programs: cities like Norfolk, Virginia; Austin, Texas; San Jose, Calif.; and Philadelphia, all have small business and downtown development programs which offer incentives on capital improvement projects - and all specifically mention awnings as desirable (and incentivized) options. A municipal program can pay anywhere from 25% to 50% of the cost of the retractable awning.
In addition to the practical reasons, Europe has had a long aesthetic tradition with awnings, so retractable awnings are a natural part of any home design, and that organically led into creative and adventurous designs, which made using awnings even more appealing. The US, on the other hand, has had historically cheap and accessible energy, with widespread air conditioning and central air systems. Combined with suburb-motivated home designs, neither energy nor aesthetics has given a compelling reason to include retractable awnings on homes as a standard practice. Energy shortages and price increases in the 1970s, though, did begin bringing retractable awnings to the popular mind as a functional solution for energy efficiency.
